The purpose of this research was to analyze the trajectory of child's academic attainment and the effect of family socioeconomic background on the trajectory. Data were part of the Korea Youth Panel Survey 2003-2005(Middle School 2) and were analyzed by Latent Growth Curve Modeling(LGM). The degree of child's academic attainment decreased over 3 years. Socioeconomic status variables that influenced academic trajectory were family poverty, parent's attainments in scholarship, and family structure. Findings from this study suggest that societal support for low socioeconomic status families is needed for improvement of academic attainment of their children.

This study was carried out to determine the characteristics of the marine environment, including nutritional content, in order to clearly understand the outbreaks of Gonyaulax polygramma in the southern coastal areas in August, 2009. Samples were collected at 13 sites and water temperature and salinity were measured using a CTD. Field surveys were twice: the first between August 5-7, the second between August 22-24. The cell density of G. polygramma was 6,500-10,000 cells $ml^{-1}$ during the $1^{st}$ survey, whereas during the $2^{nd}$ survey the range of the cells was recorded from 8,000 to 12,500 cells $ml^{-1}$. Cochlodinium polykrikoides ranged from 0 to 105 cells $l^{-1}$ during the field survey. In water environments, the majority stations during the $1^{st}$ survey showed a nearly homogeneous water column below $1^{\circ}C$ in temperature, as well as similar profiles of salinity. However, the stratification between the surface and bottom was observed in the $2^{nd}$ survey. Regarding nutrients, Dissolved Inorganic Nitrogen (DIN) in the surface ranged from 0.144 to 0.236 mg $l^{-1}$ during the $1^{st}$ survey, and 0.082-0.228 mg $l^{-1}$ during the $2^{nd}$ survey. DIP (Dissolved Inorganic Phosphorus) did not show any difference in concentration between the $1^{st}$ and $2^{nd}$ survey. During August of 2009, the wind speed in the southern waters remained at around ${\leq}2\;m\;s^{-1}$ for about 60% of time, and there was very little precipitation during the month. Irradiance of ${\geq}10$ hr was shown in the late of August. It is thought that a low level of DIN and salinity play an important role as an essential factor for rapid growth, wide distribution and longer duration of red tide in G. polygramma.

Purpose - This research aims to examine the effect of e-business adoption on firm's growth and profitability in the distribution industry. The value added from the distribution industry acts as the cost of other industries. As the distribution industry develops, its stage becomes shorter and the distribution margin becomes smaller. Therefore, e-business is expected to have a different effect on the distribution industry than other industries. Research design, data and methodology - The previous research generally used e-business adoption as an independent variable and firm's performance as a dependent variable. This study elaborated the model using a dynamic panel model that includes the performance variable of the previous year as an independent variable. By employing system GMM (Generalized Method of Moments), the endogeneity problem in the dynamic panel model can be solved. For the analysis, I extracted the distribution companies as the raw data in the National Statistical Office's Business Activity Survey over the period 2006 to 2012. Results - The growth rate of firms adopting e-business was 0.299%p higher than that of the non-adopter. However, only ERP (Enterprise Resource Planning), KMS (Knowledge Management System) and SCM (Supply Chain Management) contributed positively to the growth rate. In the case of profitability, it was 0.04%p higher than the distribution companies that did not adopt e-business. ERP and LMS (Learning Management System) improve profitability, while SCM reduces profitability. Consequently, while ERP improves both growth and profitability, SCM improves growth but reduces profitability. In addition, KMS improves firm's growth only, and LMS does only profitability, showing that each e-business has a differentiated effect. Conclusions - Since the distribution industry has different characteristics from manufacturing and other service industries, the introduction of e-business may not guarantee the growth and profitability of distribution companies. Careful introduction considering the characteristics of the distribution industry is required. In particular, it is necessary to select an e-business meeting the characteristics and needs of a distribution company, and thereafter, it is required for the company's own efforts to internalize it within the system.

본 연구는 우리나라에서의 경제성장과 빈곤간의 관계에 대한 실증적 연구결과를 제공하는 것을 그 목적으로 한다. 특히 외환위기 후 2000년대 들어 경제 성장과 빈곤간의 관계에 어떤 변화가 발생했는지를 검토한다. 이를 위하여 도시가계조사 1982-2004년 원자료를 이용하여 도시지역의 빈곤율 연간자료를 구축하고, 거시경제지표로서 실질GDP와 실업율의 연간자료를 이용하였다. 분석결과 1980-1990년대에 걸쳐 우리나라에서 거시경제성장은 빈곤감소에 아주 직접적이고 중요한 역할을 담당한 것으로 나타났다. 2000년 이후에도 거시경제성장은 여전히 빈곤감소의 주요한 도구로서 작동한 것으로 나타났다. 그러나 1980-1990년대에 비해 2000년대 이후에는 거시경제성장에 의해 설명되지 않는 빈곤의 증가현상이 존재한 것으로 나타났다. 이러한 분석결과는 향후 반빈곤전략이 과거의 경제성장 우선전략에서 경제성장과 함께 사회보장제도 확충을 동시에 강조하는 전략으로 전환되어야 한다는 것을 제시한다.

This study classified the current work-life balance of full-time female paid workers and tested the typology by using the 2009 Korean Time Survey. The categorization demographic and psychological characteristics of women belonging to each type were comparatively analyzed. It was found that full-time female paid workers used an average of 435.7 minutes for work, 146.4 minutes for family, 104.5 minutes for leisure, and 17.7 minutes for growth. On the basis of times used in each area of work and life, individuals were classified into family-oriented type, work-leisure parallel type, work-oriented type, work-growth parallel type, and work-family parallel type. Psychological characteristics were examined by type. The work-oriented type women experienced feelings of lack of time and fatigue the most compared with women of other types. From examining the influence that the amount of time used in each area of work and life had on psychological characteristics, it was shown that the activity time relevant to leisure influenced psychological characteristics the most. Lastly, based on the limitations of this study, future assignments are discussed.

The purpose of this research was to investigate the relationship between employee engagement and individual performance outcomes (including growth, achievement, contribution, and customer satisfaction) in large firms in Thailand, which is rapidly growing as an international business hub. The study took place in Thai offices of multinational corporations, whose performance is both very important for Thailand's overall economy and for the firm's continued presence in Thailand. The study was conducted using a survey methodology. A convenience sample of employees of multinational corporations (n = 423) completed a survey on employee engagement and individual performance outcomes. The data were analyzed using linear regression analysis. The results showed that there was a significant, positive relationship between employee engagement and all four performance outcomes that were targeted. The strongest effect was observed for achievement (β = 0.899), followed by growth (β = 0.887), contribution (β = 0.872), and customer satisfaction (β = .867). These findings indicate that employee engagement is a significant and strong factor that determines the individual performance of employees of multinational corporations. This implies that companies do need to consider how to promote employee engagement. There were some limitations, especially social response bias and the self-reported nature of performance, that limit these findings.

This research was conducted to identify factors that affect work-life balance and happiness among married working couples with a double income. To this end, a survey was administered to 260 married working couples in the Seoul metropolitan region. The analysis of the survey responses using the SPSS (Ver. 21) program yielded several important results. First, the variables that significantly affected work-family balance included the number of family dinners eaten together, meaning of life, efforts to strike a work-life balance, and the availability of social institutions and policies that promote work-life balance. Variables that significantly affected work-leisure balance included meaning of life, number of family dinners eaten together, gender, and the availability of social institutions and policies that promote work-leisure balance. As for work-growth balance, significant variables included meaning of life, communication with colleagues, income, and meaning of work. Finally, variables that significantly affected happiness included meaning of life, income, communication with colleagues, and work-growth balance. Based on these results, follow-up research needs to be conducted on various groups to help determine the factors that will ensure their work-life balance and happiness.

Purpose: This study investigates the moderating effect of mindset types on experience and perceived quality in virtual reality (VR) contexts and identify the relationships among mindset types, experience, perceived quality, attitude, and purchase. Research design, data and methodology: Using a survey, a total of 250 participants were recruited from South Korea. Participants were asked whether they have been VR users who had experienced VR before participating in the survey. We used the partial least squares method to test the hypotheses based on structural equation modeling. Results: The results show that experience, including spatial, reality, and sensory experiences, has positive effects on perceived quality. Additionally, the mindset moderates the relationship between experience and perceived quality such that consumers with experience are more likely to have greater perceived quality when they have a growth mindset compared to those with a fixed mindset. The VR context's perceived quality exerts positive effects on attitude toward the VR context, while attitude has positive effects on purchase intention. Conclusion: We suggest that the consumer's mindset might work as an essential moderating factor that influences the relationship between experience and perceived quality. Our findings can help marketers plan promotion strategies more effectively and cater to the different objectives of their contexts.
